it's odd you don't understand that as you give crystal clear definitions
yourself, space is what a ruler measures and time is what a clock measures.
Zero ambiguity in that.

Then we'll never know it's right without an experiment that can confirm it,
 and experiments can't exist without rulers and clocks.

So what? Everything is made of something else unless you're at the
fundamental level. Space and time may not be made of anything but at least
they're measurable, I don't see how claiming the fundamental level is mot
made of anything and is not measurable either get's you anywhere; you could
theorize it's made of anything you like and it would still be consistent
with any conceivable experiment. In other words its just navel gazing.
